90+2min: It's not going to happen though, as Varela is booked for a foul on the Manchester United byline. Don't expect Wolfsburg to rush this set-piece...

21:35

90min: United have three minutes to do what they did to another German team 16 years ago - score two goals in stoppage time.

21:33

88min: Back come United, but the ball just won't go in as Martial and Smalling are denied by superb Wolfsburg blocks.

21:28

GOAL! PSV 2-1 CSKA Moscow

United are not on the brink any more, they are as good as out the Champions League! PSV now lead CSKA Moscow as Davy Propper hits a 25-yard half-volley home with four minutes left.

United now need TWO goals to go through.

21:28

GOAL! WOLFSBURG 3-2 Manchester United

84min: But immediately Wolfsburg hit back, Naldo converting from another set-piece to put United on the brink once again.

21:26

GOAL! Wolfsburg 2-2 MANCHESTER UNITED

83min: Oh what drama! From the resulting corner, Fellaini's header is knocked on by Josuha Guilavogui into his own goal. United are heading through as it stands!

21:25

81min: Memphis darts down the left, shrugging off Trasch, before forcing a corner at the near post with his low effort.

PSV Eindhoven's Luuk De Jong equalises for his side against CSKA Moscow

21:25

78min: The bad news keeps on coming for Manchester United. Chris Smalling appears too injured to carry on but United have already used all their substitutes.

After a short discussion with Van Gaal, the United defender gingerly jogs back on to the pitch to continue.

United MUST score inside the last 12 minutes to avoid dropping into the Europa League, unless CSKA Moscow can strike again.

21:21

GOAL! PSV 1-1 CSKA Moscow

Incredible. Manchester United are heading out of the Champions League again as two minutes after falling behind, Luuk de Jong pounces on horrible CSKA defending to prod home inside the box.

21:18

GOAL! PSV 0-1 CSKA MOSCOW

HUGE news from PSV. Sergei Ignashevich has scored a penalty for CSKA which means as it stands Manchester United are now going through!

21:18

PENALTY (CSKA Moscow)

21:17

73min: Ah just wide! I thought it was in as Memphis struck the free-kick but it whistled just wide across the target.

21:16

72min: Naldo is booked for Wolfsburg, and will miss their next European match, after bringing down Martial right on the edge of the box.

21:14

Double Manchester United substitution

69min: Suddenly it's all Wolfsburg as an unmarked Max Kruse blasts a volley just wide while unmarked from a cross. Huge let off for United who make their final two changes as Nick Powell and Michael Carrcik replace Mata and Schweinsteiger.

Sir Alex Ferguson shows a look of dejection in the stands at the Volkswagen Arena

21:12

67min: De Gea to the rescue again. Wolfsburg's one-touch play is too hot for the United defence to track or handle as Draxler's first time pass to Schurrle inside the box results in the forward's rising drive being tipped over by the United keeper.

21:09

65min: Zero to hero - all inside ten seconds! David de Gea dashes madly out his goal and as Schurrle attempts to lob the United keeper from 30 yards, the Spaniard sprints back before somehow clawing the ball out for a corner at full stretch. Magnificent save even if it all came about from his own error.

21:06

62min: That's more like it from United! A short free-kick results in a low shot being deflected towards the far post where Mata just misses out on diverting the ball home. He was offside anyway, but the United pressure is increasing - they actually look a threat now.

60min: So of course the next slice of action sees Benaglio make a wonderful save. United finally get the ball into the mixer, with Memphis's strike across magnificently beaten away by Benaglio.

21:04

57min: Wolfsburg appear to be settled into a defensive shape, albeit one looking to hit United on the counter attack.

The home side are in a commanding position really. Even a draw would send them through and in truth they look in no danger of conceding.

20:59

54min: It's been a promising ten minutes but nothing more from Manchester United. There is a lack or urgency in their play as Wolfsburg comfortably soak up this light United pressure. Benaglio has had nothing to do this half.

Bastian Schweinsteiger of Manchester United takes instructions from the touchline

20:57

51min: Of course United MAY Have help in Holland from CSKA Moscow. If the Russian side win at PSV, United would be back in last 16 contention. It's 0-0 in Eindhoven.

In Germany, United are still pressing for an equaliser without much success so far.

20:53

48min: Good start to the half for Manchester United who must score two goals to secure a result they know would take them through.

Memphis Depay wins the ball on the Wolfsburg byline but his cut-back into the box fails to result in a shot on target.

39min: It should be 3-1! It's De Gea to the rescue for Manchester United as Julian Draxler helps Wolfsburg break forward before cutting inside and seeing a low shot parried by the Manchester United keeper.

20:23

From Sportsmail's Joe Bernstein at the Volkswagen Arena

'A Liverpool-United Europa League final in Basel, anybody? With Roger Federer presenting the trophy to either Jordan Henderson or Wayne Rooney.'

20:22

36min: That Fellaini header looks rather pivotal now. Wolfsburg continue to attack with freedom as Schurrle leaves the United defence in knots on the left before winning a corner.

Vieirinha (centre) scores the second goal for Wolfsburg following a fine passing move

20:21

33min: So as it stands, Manchester United will be OUT of the Champions League. It's still 0-0 in Eindhoven which would put PSV level on points with Van Gaal's team.

However, PSV have a superior head-to-head record against United thus would progress along with Wolfsburg.

20:18

From Sportsmail's Joe Bernstein at the Volkswagen Arena

'United fans will be wanting their boring Louis van Gaal back. Three goals in the first half-hour, but their team have conceded two of them. The defensive solidity and shape has gone.'

20:15

GOAL! WOLFSBURG 2-1 Manchester United

29min: This has to be one of the best goals in the group stage so far. A fine passing move rips open United's defence before Vieirinha taps home from inside the box. Incredible fluidity in the Wolfbsurg attack there - they made it look so, so easy.

20:11

25min: Through your legs! Surrounded by defenders, Martial performs a neat nutmeg on Christian Trasch before winning a corner, but the set-piece directed at Bastian Schweinsteiger is cleared by the hosts.

Manchester United's Juan Mata (right) misses out on making low contact with a cross

20:09

22min: Since Martial's goal we haven't seen too much from Manchester United in an attacking sense. It's Wolfsburg pressing for the next goal but there isn't much to choose between the teams at the Volkswagen Arena.

20:07

19min: Matteo Darmian is booked after bringing down Vieirinha, but with no Rodriguez now on the pitch to hit sweet free-kicks, Josuha Guilavogui's delivery is harmless as it floats out for a goal kick.

Naldo of Wolfsburg celebrates after scoring a goal to level the scores at 1-1 against Manchester United

20:03

Wolfsburg substitution

16min: But it comes as a price for Wolfsburg as Rodriguez now has to depart through injury as he is replaced by Marcel Schafer. As far as the group stands, it's as you were before kick-off with both these teams going through.

19:59

GOAL! WOLFSBURG 1-1 Manchester United

13min: He plays centre-back?! Wolfsburg are level after just three minutes behind as Naldo fires home a sensational volley following a Ricardo Rodriguez free-kick pumped forward into the box. The technique is masterful, a contrast to United's marking from the set-piece.

19:59

13min: As it stands United will go through as group winners, and they would be taking Wolfsburg with them as it is still 0-0 in Eindhoven.

MARTHA KELNER: Manchester United's Champions League tie at Wolfsburg on Tuesday night is crucial for a number of reasons, not least because it is the only way they can be certain of progressing in the competition.

A victory could win over fans who have become disenchanted with their ‘boring’ play and avoid slipping into the Europa League with its nuisance Thursday night matches.

Defeat could leave them not only counting the symbolically damaging nature of an early exit but also the financial loss, long after the final whistle.

Manchester United face Wolfsburg in what could be a must-win Champions League clash for Louis van Gaal's side in Germany.

The Red Devils will top Group B with a win over leaders Wolfsburg but they will crash out of Europe's top tier competition if they fail to either match or better PSV Eindhoven's result against CSKA Moscow.

United could lose up to £50million if fail to qualify for the last 16 of the Champions League.

Follow all the action with Sportsmail's Dan Ripley ahead of tonight's 7:45pm kick-off.
